PARK TOOL TOOLS
Building your own wheels or replacing spokes can be an easy and rewarding experience. A trueing stand may be the first tool you need to achieve this, but the Park Tool TM-1 Spoke Tension Meter is a close second. The TM-1 gives you accurate and reliable measurements on nearly any bicycle spoke -- regardless of diameter, material, or shape. It measures the absolute tension of each of the spokes in a wheel, as well as the relative tension between them. The TM-1 is a tool that belongs on every workbench.
